- Sensory memory is taken in from the environment, it lasts 1-2 seconds and then if no attention is given to it, then the information is forgotten
- If information is given attention then it is passed on into the short term memory, which can hold 5-9 items at a time
- There the information lasts 15-30 seconds before it is either forgotten by displacement or moved on into the long term memory
- Information is moved to the long term memory by rehearsal and there, the capacity is infinite so can hold a great deal of information
- However, this information can be lost through lack of use (decay) or interference (confusing information)
